/M/ENTOR aff/vm.: s .5. sHLLa/vaffrem Y MVM/MHTTY and .2, thus serving to materially strengthen the ends of the buer beam andthe forward corners of the car endunderv frame. I

Formed`integral with the forward porltions 'of the center sills 4 is a horizontally disposed plate 16, .and formed on the top l"thereof by means of four vertically disposed Walls `is a pocket lZvadapted to v.receive the y springs and follower plates which are low cated upon the central one of the butl'er stems utilized in connection with my 1mproved under frame. lThe central butler stem (not shown) op- 4 Vcrates through alinedopenings 18 formed in the front and rear walls of the butter beam 11, and through the front wall of the pocket 17 and the side butler stems operate through alined openings 19 formed through the front and rear walls of the butter beam 1l.

The sills of the car body rest directly upon and are attached in any suitable' manner to my improved car end underframes, andthe endsof said sills bear directly against the rear wall' of the buffer beam 11. Thus a very solid and substantial support is formed for the end portions of the car body, and all buffing and pulling strains upon the buffing beam, and said underframes, are distributed over areas of considerable extent at both ends of the car body. f

In the modiied construction illustrated in Figs. 4 and 5 an extension 20is formed integral with or xed to the rear side of the bolster 1, and which `extension serves as a 'bearing Vfor the attachment of the center draft sill, or sills of the car body underframe. This extension is preferably of` in- Verted U shape in cross section, or it may be of box form in cross section, and the top plate of said extension preferably occupies the same horizontal plane with the top plate or flange of the bolster 1. The center draft sill or sills of the car body underframe are rigidly fixed in any suitable manner to the extenstion 20, and thus said sills are in direct -alinement with the center sills 4 of my improved ear end underframe, and by such arrangement all bufiing and draft strains iml parted to the car end underframes are transmitted directly to the car underframe draft sills which extend longitudinally beneath the car body, and unite said car end underframes. l

A car end underframe of my improved construction is comparatively light in weight, and by reason of its being formed in a single piece combines strength with rigidity, is inexpensive, can readily be installed and is practically designed to lresist all 5@ strains to which it may be subjected while ini/service.

IIt will be readily understood that various changes in the construction and combination of-my im roved device may be made and @5 substituted) for those herein shown and de scribed without departing from the spirit or my invention, the scope of which is set forth in the appended claims.

I claim: Y

1. ln a car end underframe, the combina- 7e tion with an integral structure comprising bolster` an end sill, side sills, a pair of center sills, diagonally disposed brace. members arranged between the central portion of the bolster and the end portions of the end sill, of a hollow box shaped butter beam integral with the end sill, the bottom plate of which buller beam occupies the same horizontal plane with the' top plate of the end sill. 8O

2. In a car end underframe, the combination'with a one piece cast metal structure' comprising a bolster, an end sill, side sills, and a pair of center sills, of a hollow box shaped bui'er beam integral with the end 85 sill, the bottom plate of which butler beam occupies the same horizontal plane with the top plate of said end sill. u

3. In a car end underframe,v the combination with a one piece cast metal structure comprising ai flanged bolster, a flanged end sill, anged side sills, and a pair of flan ed center sills, of a hollow box shaped bu er beam inte ral with said end sill, the bottom plate ofw iich butler beam occupiesv the same horizontal iplane with the upper flange of said end sill. 4. In a car end underframe, the combination with a one piece cast metal structure comprising a flanged bolster, a flanged end sill, lianged side sills, a pair of flanged cen-y ter sills and a pair of diagonally disposed brace members arranged between the central portion of the bolster and the end portions of the end sill, the forward ends of the webs of which brace members extend forwardly to the end sill parallel with the webs of the side sills, of a hollow box shaped buffer beam integral with the end silland which bulfer beam occupies a plane above the' plane occupied by the underframe.

5. In `a car end underframe, the combination with a one piece cast metal structure comprising a Hanged bolster, a channel shaped end sill, inverted L-shaped side sills, and a pair of channel shaped center sills, of a hollow box shaped buffer beam integral with said end sill, the bottom plate of which buii'er beam occupies the same hori zolnta'l plane with the top flange of said-end si l.

v6. In a car end underframe, the combination with a onepiece cast metal structure comprisinfr a flanged bolster, a channel shaped en sill, a pair of inverted L-shaped -side sills, a pair of ch'anzlel shaped center sills` a lpair of flanged diagonally disposed brace members extending 'from the` central portion of the bolster to the' end portions of the end sill, of a hollow/"box shaped .bader 13e beam integral with said end sill and the l portions of the end bottom plate of which buffer beam occupies` the same horizontal plane with the upper flange of Said end sill.

7. -In a car end underframe, the combina tion with a east metal member having a channel shaped end sill and inverted L- shaped side sills, of a hollow box shaped buffer beam integral with said end sill, the bottom plate of which butler beam occupies the same horizontal plane with the top flange of the end sill, and the top flanges of the side sills and the end sills of which butler beam are in direct alinement with and are continuations of the vertically disposed Webs of the side sills.

8. In a carend underframe the combination with a cast member having a channel shaped end sill and inverted L-shapcd side sills, of a buffer beam integral with and occupying a plane above the end sill, and the end walls of which buffer beam are in direct alinement with and are' continuations` of the vertically disposed webs of the side-1 sills.

9. In a car end underframe the combination with a east member having,f a bolster, a pair of side sills, an end sill and diagonally disposed brace members between the central portion of the bolster and 'the end sill, of a hollow boxshaped buffer beam integral with the end sill, the bottom plate of which butler beam occupies the same horizontal plane with the top plate of the end sill portions of which diagonally disposed brace members extend forward parallel with the side sills to form braces for the ends of the buffer beam and braces integral with the underside of the butler beam and with the front'side of the end sill.

10. In a car underframe, the combination with a one-piece cast metal structure comprising a bolster, a rearward extension on the central portion of said 'bolster for the attachment of the center draft sills of the car body underframe, an end sill, side sills, and a pair of center sills, of a hollow boxshaped buffer beam integral with the end sill, the bottom plate of which buffer beam occupies the same horizontal plane with the top plate of said end sill.
